Please EDIt your question to somehow explain who or what TOEFL, IELTS and GRE means ... E.g. by adding an hyperlinks or at least a description of these Acronyms ...

I'm on mobile so I'll add them later. But aren't those acronyms obvious? At least for TOEFL and IELTS. And even if there is someone doesn't know, they should already know that those are the names of exams.
